Some people are so worried about the weeds in the yards of others to the extent their yard gets out of control. Before they know it – - when they look down they are knee high in grass, weeds and who knows what else.
If they cannot see what is in their knee high grass, then how do they know what is in it?
For all they know they could have snakes and other deadly things in their grass.
If more people worked on keeping their yards tidy, they would not have the time to worry about the yards of others.
Bottomline: If you are not a professional and do not have years of proven experience maintaining yards, don’t give advice.
